[Primary cerebral lymphoma. Current status of diagnosis and therapy]

Primary cerebral lymphomas are rare tumors. In the last years the frequency of these space occupying lesions is increasing. Diagnosis by image-generating methods is often difficult. Stereotactic biopsy is a reliable diagnostic tool. Explorative craniotomy with tumor resection should be avoided if possible. An effective multimodal therapeutic regimen is the combination of radiotherapy and chemotherapy. Epidemiologic data, diagnostic methods and therapeutic proceedings are presented and discussed on a series of 7 patients with primary cerebral lymphomas treated in our department.
